APPARATUS FOR EXTRACTING OIL,

SPECIFICATION forming part of Letters Patent No. 761,686, dated June *7, 1904.

d Application filed February 8, 1902. Serial No. 93,186- (No model.) i I T @ZZ whom it 7er/ty concern:

Thisinvention relates to certain improve-` ments in apparatus for extracting oil from cotton-'seed meal; and the object of the invention is to produce a machine of this character which will be capable of receiving the meal through a suitable hopper or chute and extract the oil preferably by a continuouslyoperating mechanism, so that the meal may be delivered at one portion of the machine and acted on, so as to extract the oil therefrom and deliver the meal and .oil separately.

In my preferred form, ets-illustrated in the accompanying drawings, the machine is of a rotary character and receives the meal into various pockets in a revolving drum, and the latter, through the aid of plungersand cams, acts to squeeze the meal and deliver the oil into any suitable receptacle, while the meal (now very dry and in the form of compact cakes) may be deliveredV onto an endless apron, from which the cakes are'transferred to any predetermined place.

In the accompanying drawings, which represent the preferable embodiment of my invention, Figure 1 is a vertical cross-section of my apparatus. Fig. 2 is a vertical section taken at right angles to that shown in Fig. 1. Fig. 3 is a detail sectional view of one of the plungers and pockets on a much larger scale. Fig. 4 is an elevation from the inside of one of the end frames, showing the partial cylindric casing in section. Fig. 5 is a vertical section of one of the side frames and part of the cylindrical casing, and Fig. 6 is a sectional detail of a portion of o ne of the plungers on a much larger scale.

Referring now to the details of the draw any desired construction. Situated between 2 and 5.

these frames 1 and 2 is a casing 6 of cylindrical form, and the side frames are bolted to this casing, as clearly shown at 7 in Figs. This casing does not extend entirely around the space inclosed by the side frames 1 and 2, but has a gap of preferably about one-fourth of its circumference, as shown in Figs. 1 and 4, for a purpose to be hereinafter described. Within this casing 6 is rotatably supported a hollow drum 8, provided with annular extensions forming journals 9 and 10, which pass through and are journaled in openings in the side frames. The journal 10 is somewhat longer than its companion 9 and has a wormwheel 11 keyed thereto, ,and this worm-wheel meshes with a worm 14, operated through the shaft 17 and pulleys 15 and 16, to which power may be applied in any convenient manner.

The aforesaid hollow drum 8 is formed with a series of radially-disposed pockets or openings 19, which extend toward the central opening andare open at the periphery of said drum. In each of these pockets is a plunger 20, arranged to slide in and out of the pockets, each plungerbeing formed T-shaped, as shown in Fig. 3, and the stems 21 of the plungers 2O are arranged to slide in similarlyshaped parts 22 of the pockets 19. All of the pockets are open at each end, and all of the plungers have trunnions 24 formed on both of their ends, which trunnions are for the purpose of supporting rollers 25, which may be held in place by means of plates 26 and screws 27,V as shown in Figs. 2 and 6.

The side frames 1 and 2 are provided with annular grooves or recesses 30 and 31,v and the lower portions of these grooves or recesses are channeled out to form oil-pockets 32 and 33, these pockets being provided with tubes 34 and 34 to deliver the oil from the oil-pockets 32 and 33 into any desired receptacle or storage-chamber. (Not shown.)

The aforesaid grooves or pockets SO'and 31 are each provided with an annular shoulder 36, (see especially Fig. 5,) and cams 38 and 39 are secured to the side frames land 2 by means of screws 40. The cams are of the peculiar shape illustrated in Fig. 4, from which figure it will be seen that the cams, beginning with the point marked a, gradually grow larger from the airis of rotation until the point b is reached, and from this last -mentioned point the cams are of uniform size around to the point c, where it will be noticed that a hump d is provided. The cams are formed in the manner illustrated, so as to act on the rollers journaled on the plungers in order that the plungers may be forced outward in the peculiar manner hereinafter described.

On the top of each of the plungers 20 is bolt* ed a pressure-plate 35, which is formed in the peculiar manner illustrated in Figs. 3 and 6. Each of these plates is longitudinally grooved, as seen at 36, and these longitudinal grooves lead into the larger openings 37 through the small passages 38, and between the pressure-plates 35 and the plunger 2O a large opening 3S is left, into which the oil which is extracted from the seed or meal may pass. Each of the pressure-plates 35 is also provided with tubes 40, which rotate with the plungers and pressure plates and afford a means of permitting the oil to pass from the openings 39 into the oil-pockets 32 and 33, as will be seen from inspecting Fig. 2. As there is great pressure on these pressure-plates 35, I prefer to strengthen them by lugs 42, as clearly seen in Figs. 3 and 6. The surfaces of each of these pressure-plates 35 is covered with camels-hair mats 41, which are usually employed for this purpose, these mats being of such a nature as to furnish the proper strength, and yet permit the oil to sift through them.

In order to keep the seed or meal in aheated condition while the oil is being extracted therefrom, I form a water or steam jacket around it, which may be seen in Figs. 1, 2, 4. and 5. In the form in which I prefer to make it the heating fluid may be forced through an inlet 44, from which it passes through the cir- Y euitous passage 46 and out of the outlet 47,

(see Fig. 2;) but this of course may be varied to suit the pleasure of the manufacturer.

In order to properly deliver the seed or meal to the pockets, I employ a hopper or any suitable seed-chute, which, as shown in my drawings, consists of a delivery-tube 50, which is secured immediately over the hollow drum 6 and between the side frames 1 and 2, as seen in Figs. 1 and 2.

I have hereinbefore described the cylindrical casing as being open for about onefourth of its cireumference,and this cylindrical casing and the side frames 1 and 2 are beveled off, as shown in Figs. 1 and 4, and to the upper beveled part 51 I securea scraper 52, formed with a knife-edge, and to the lower beveled part 53 I secure a suitable inclined guide 54, which is arranged to deliver cakes from the pockets onto an endless apron 56, as shown in Fig. 1, so that the cakes may be carried away from the machine and delivered at any suitable point.

The operation of my apparatus may be described as follows: Power being applied to the pulley 16, the hollow drum 3 is given rotary movement through the medium of shaft 17, worm 14, and worm-wheel 11, and the endless belt 5G is driven in any suitable manner. (Not shown.) The cotton-.seed meal is delivered to the tube 5() in a heated state, and as the hollow drum 8 is rotated and the pockets therein pass underneath said seed-tube 50 the meal is progressively fed into said pockets. At such times as the pockets are under said meal-tube 50 the rollers on the plungers are acting on the lowest part of the cam 3S), and hence the plunger, then under the feed-tulw 50, is inthe lowest position in its pocket, as clearly shown in Fig. 1. As the drum is slowly rotated the pockets pass from under said feed-tube 50, and the rollers traveling around the cam 39 are gradually forced outward, carrying with them the plungers, so as to gradually compress the meal and squeeze the oil therefrom through the openings be, 37, and 38 into the larger opening 33, and as soon as the hollow drum is rotated to bring` the feed-tubes of each plunger into or rather below a horizontal line the oil contained in said openings 33 is delivered from the tubes 40 into the pockets 32 and 33, from which it passes through the tubes 34 and 34 into any suitablereceptacleorstorage-chamlier. From an inspection of the cams shown in Fig. 4 it will be seen that after the point is reached the cam is of uniform size until the point e is reached. This is for the purpose of forming the cotton-seed meal into a compact cake and holding it in such form for a long enough period of time to retain such form. As soon as the rollers reach the point marked c they are forced outward through the mediuln of the hump (Land this outward action of the rollers of course forces the plungers out yard, carrying with them the pressure-plates, eamels-hair mat, and the dried cake. The hump on the cam is of the proper height to push the cake outward far enough to be shoved oil' of its camels-hair mat by the scraper rl`he cake then falls by gravity, and as its falls onto the inclined guide 54 it is gui `lcd to fall onto the endless apron 56, by which it may be delivered to any suitable place. After the rollers pass the outward incline of the hump (Z the plungers are permitted to recede on the inward incline of the hump by gravity, as in a fullfsized machine the plungers are quite heavy.

From the foregoing and the accompanying drawings it will be seen that I have invented a eontinuously-operating machine which is admirably adapted to its purpose of receiving the cotton-seed meal and treating it seas to deliver the oil therefrom into any desired receptacle and at the same time form the meal itself into compact dried cakes, which being formed under great pressure and held there IOO llO

for some little time retain'their shape so well as to permit them to be shipped to places, when they may further utilized.
